Women's ThermoAscent Jersey - Cranberry


The Women's ThermoAscent Jersey - Cranberry

For those who seek warmth while climbing high through deep winter. The ThermoAscent Jersey. A deep winter super warm long sleeve thermal jersey designed to insulate the body and keep you warm in temperatures down to 2c. (35F) 

A women's specific garment made with a brushed, fleece-lined Italian 'Stelvio' Fabric, the ThermoAscent Jersey offers excellent thermoregulation and moisture management capabilities.

A close-fitting but high stretch jersey, our high collar keeps cold air away from the neck and chest, whilst tight wrist cuffs keep the cold from your arms and wrists.

3 large rear pockets provide ample space for winter essentials, plus a 4th water repellent zipped pocket for valuables keeps things safe and dry. A large deep reflective strip on the rear pocket keeps you seen in the dark or low light, and the black pocket fabric prevents mud or road spray from spoiling the aesthetic of your new jersey.

    Spring and autumn kit purchase

    I ordered both the merino base layer and the Thermo Ascent jersey ready for the autumn. I ordered a medium in both but switched them out for a large as both were a little too snug. Very simple exchange process via Collect+. Great quality fabric on both - jacket is warm fleece lined. The only thing stopping me giving the kit 5 stars is that the sleeves are too long on the jacket (but perfect on the base layer) and the concealed pocket on the jacket back right hand side only goes down about a centimetre before it snags on the top of the pocket seam and needs a considerable amount of force to push past - I have concerns about it malfunctioning especially if you have stuff in the right back pocket.

    Comfort but look lost

    Feel and comfort is good but due to contact with my gloves, which have Velcro fastening the finish of the top has been affected. This is only after one wear.
    Don’t bring this top into contact with Velcro

    Must Have

    Warm enough for cold days and cold enough for warm days. Used with a base layer during a 6 degrees temperature and was so good
